! DEMOUN'IABLE RIM.

Specification of Letters Patent.

Patented June 29, 1920.

Application filed August 1919. Serial No. 318,497.

To all whom it may concern:

Be it known that I, BENEDE'ITO TAMBU- RELLO, a citizen of the UnitedStates of America, residing at New York city, county and State of NewYork, have invented certain new and useful Improvements in DemountableRims, of which the following is a full, clear, and exact description.

This invention relates to improvements in demountable rims, one of theobjects being to provide an interchangeable rim, that is to say, a rimarranged to receive a straight side-tire or a clencher-tire. Toaccomplish this result, I provide a rim having detachable and reversibleflanges to engage the headings of tires. When in one position relativeto each other the flanges will be adapted to engage straight side-tires,and when in the other position they will be adapted to engage clenchertires.

Other features of improvement will hereinafter appear. I will nowproceed to describe my invention in detail, the novel features of whichI will point out in the ap pended claim, reference being had to thedrawing, wherein,

Figure 1 is a sectional view of my improvement arranged for clenchertires;

Fig. 2 is a similar view of the device arranged for a straight sidetire; and

Fig. 3 is a side view of a wheel equipped with my improvedrim.

As herein arranged, my improved rim consists of a plurality of annularbandmembers 5 and 6 and a plurality of shiftable detachable curvedflange members 7 and 8 together with fastening elements or screws 9. Inpractice the band members will be slipped on to a felly 10 of a wheel,and the removable band 6 will be slipped over the band 5 and will restupon projections 11 to maintain the band 6 clear of the band 5 toprevent rusting. The inner band 5 carries a concentric annular shelfportion 12 raised sufliciently from the band 5 to be flush with the band6, that it to say, the top surfaces of said shelf and band will beflush. The shelf 12 and band 6 each carry a flange 13 and respectively,to serve as a backing for the tire engaging flanges 7 and 8. When in useone tire-flange will rest upon the shelf 12 and the other upon band 6.lYhen the tire is pumped up the flanges or rings and 8 W111 be forcedagainst the adj)acent flanges of their respective band memers.

As the flanges 7 and 8 are removable from the band-members 5 and 6, theymay be reversed. In other words, they can be placed upon the bandmembers with the convex portions outwardly or inwardly. When the flanges7 and 8 are placed upon the bands w th the convex portions outwardlythev Wlll be adapted to engage straight side tires. When placed upon thebands, with the convex portions inwardly, the flanges will be adapted toengage clencher tires. The rim as a whole may be secured to the wheel bythe usual Wedges 10 and bolts 10*. The rim can be removed from a wheelafter the wedges 1O have been removed, this fastening means being wellknown. It will be evident from the foregoing that my improved device iswell adapted for use in connection with straight side or clencher tires,by merely reversing the position of the tire engaging flanges. After therim, as a whole, has been removed from a wheel the band members can betaken apart, after the screws 9 have been removed. The outer tireengaging flange will of course slip off when band 5 is removed.

Having described my invention what I claim is: I

1. A tire supporting assembly consisting of a band to engage a wheel, araised annular shelf carried by the said band concentric therewith,upstanding projections carried by said band a second band removablysupported by the first named band and resting upon said projections,said second band being flush with said raised shelf, a tire engagingflange removably supported by said shelf, a second tire engaging flangecarried by the removable band, and an upstanding flange carried by eachband-member to engage the adjacent tire engaging flange.

2. A v tire supporting assembly consisting of a band to engage a wheel,a raised annular shelf carried by the said band concentric therewith,upstanding projections carried by said band, a second band removablysupported by the first named band, and resting upon said projection,said second hand being flush with said raised shelf, a tire engagingflange removably supported by said shelf, a second tire engaging flangecarried by the removable band, an upstanding flange carried by each bandmember to engage the adjacent tire engaging flange, and screws to secureone band to the other, said screws passing through some of saidprojections. 10 Signed at New York city, N. Y., this 15 day of August,1919.
